An operating handle 68 is secured to the projecting end of the shaft 45 which projects beyond the wall I6 being removably mounted on the shaft 45 by means of a nut 69. The handle 68 is provided with an inwardly offset extension 10 which confronts the plate 52 and the plate 52 is provided with a fixed stop member II. The stop member ii is positioned in the path of the handle extension 70 so as to limit the swinging movement of the handle 68 during the feeding stroke thereof.

The plate 52 is provided with a plurality of circumferentially spaced apart graduations l2 and indicia I3 are associated with the graduations I2. A pointer I4 is carried by the outer side of the wall I6 of the housing and the graduations '52 are adapted to determine the degree of swinging of the handle 68 so as to thereby eject a predetermined length of tape. An idler feed wheel I5 is rotatably carried by a shaft 15' which loosely engages between guide members ll carried by the wall I6 on the inner side thereof. The idler feed wheel 15 is positioned forwardly of the vertical axis of the feeding wheel 44 and is constantly urged to engaging relation with the tape engaging over the wheel 44 by means of a U-shaped spring I9. The spring 79 at the free ends thereof is provided with coils 80 engaging abouta transversely disposed pin 8I which is carried by the side walls I6 and Il rearwardly of the wheel I5. The ends of the coils 80 terminate in extensions 82 which engage the upper surfaces of the ribs 26 laterally of the longitudinal edges of the tape.

The lever or handle 68 is returned to an inoperative position by means of a lever 83 which is fixed to the shaft 45 at one side of the wheel 44 and is provided with a groove 84. The lever 83 has one end of a spring 85 secured thereto by means of an eye bolt 86. The lever 83is also provided with a substantially T-shaped head 81 which is adapted to engage a rubber bumper or stop mem ber 88 which is fixed by means of a bolt 89 to a A triangular supporting member 90. The supporting member 90 is provided with a base plate 9| fixed by means of bolts 92 to the side wall I6 adjacent the lower end thereof.

A water container 93 is disposed in the forward end of the housing I5 engaging between the side walls I6 and I1 and the container 93 is provided with a reduced extension 94 extending inwardly in a direction of the feeding wheel 44. A brush holding member 95'is disposed in the reservoir or water container 93 and a brush 96 is removably engaged with the holder 95 and is inclined upwardly and forwardly, the upper end of the brush 96 projecting above the reservoir or container 93 and engaging against a supporting wall 91 formed with the holder 95 and the front wall of the container 93. The reservoir 93 is supported within the housing I5 by means of a supporting plate 98 which is carried by vertical member 99 provided with a horizontally disposed base member I00. The base member I00 projects laterally of each side of the plate 98 and is secured to the housing I5 by fastening members IOI. The vertical extension 99 is provided with a horizontally and inwardly projecting lug I02 on which a pin I03 is mounted. The opposite end of the spring 85 is secured to the pin I03. The container 93 is yieldably held in the housing I5 by means of a spring I04 which is secured by fastening membars I 05 to the under side of the table member 22.

6,175,959 The spring or catch I04 engages an upwardly the upper end thereof which is adapted to engage stop members H5 and H6 carried by the side walls I6 and I1 respectively. The knife carrying frame I01 is constantly urged upwardly to an inoperative position by means of a pair of springs H1 and H8 mountedin openings H9 and I which intersect the channelsor guide members I08 and I09 respectively and the springs H9 and I20 are tensioned by means of set screws HI and I22 respectively. The carrier or knife frame I01 is provided with a knife I23 having a V-shaped keen edge I24 and the knife I23 is secured to the upper bar I12 bymeans of fastening members I25. The carrier I01 is positioned between the forward end of the table 2I and the rear end of the downwardly ofiset table portion 23 and is adapted to cut off a predetermined length of tape v at the forward end of the table 2i.

The carrier I01 is moved downwardly by means of a pair of pivoted levers I26 which are mounted wardly of the trunnion I21 is provided with a trigger engaging member I29 and a trigger or tripping member I30 is fixedly mounted on the shaft 45 in the path of the lever tripping member I29. During the rotation of the shaft 45 in the feeding cycle wherein the feeding wheel rotates in a counter clockwise direction as viewed in Figure 2, the trigger I30 is adapted to en gage the lever tripping member I29 to thereby raise the lever I26 within a slot I28. At this time the lever I26 is inactive relative to the -carrier I01 but after the tripping member I30 passes the lever extension I29, the lever I26 will drop downwardly by gravity to engage the lower end of a slot I28. When the handle 68 is released for return under the tension of the spring 85, the trigger-l30 will rotate in a clockwise direction with the wheel 44 stationary and will then strike the lever operating member I29 so as to swing the opposite end of the lever I26 downwardly. This will move the carrier I01 downwardly and move the knife I23 across the tape which engages between the upper portions of the side members I10. Downward movement of the carrier I81 will contract the springs H9 and I20.

and after the trigger I30 passes the lever operating member I29, the springs I I9 and I20 will return the carrier I01 to an upper inoperative position. The lever 83 is held against the resilient bumper or stop member 88 by means of a U-shaped catch I3I which is provided with flared free end portions I32 engaging about the head 81.

A removable guide plate I33 is disposed between the side walls [G and I1 above the table 2| and is provided with outwardly projecting trunnions I34 engaging in guide members I35 carried by the inner sides of the side walls I6 and I1 above the table 2i. The plate I33 is adapted to engage on the ribs 26 and is provided with a downwardly offset intermediate member I36 engaging in the guide-way 21 about the tape T.

Theunder surface of the extension I36 is posttioned in upwardly spaced relation to the upper surface of the table 2I so that the tape T may freely slide in the space between the extension I36 and the top of the table 2I. The plate I33 is fixedly held in adjusted relation relative to the table 2I by means of a longitudinally curved clamping member I31 in the form of a bowed spring which is tensioned by means of a bolt I30 which is threaded into the plate I33. The plate I33 is provided with a transversely disposed boss I39 having upwardly projecting flanges I40 between which the clamping member I31 engages. The ends of the clamping member I31 are adapted to abut against the inner sides of the guide members I35 so as to thereby hold the plate I33 against movement relative to the housing I5.

A plate I is disposed over the table 22 and is provided with an upwardly curved rear end portion I42 confronting the knife carrier I01 thereby forming'a mouth I43 to receive the end of the tape T as it passes from the table 2|. The plate MI is adapted to engage the ribs 25 with the under surface thereof spaced from the upper surface of the table 22 as shown in Figure 8 and the forward end of the plate I is provided with an upwardly inclined extension I44 terminating in a downwardly curved forward end I45. The

extension I44 and the downwardly curved portion I45 are adapted to engage over the upper ends of the brush 96 so as to hold the tape T in contact with the moistening member or brush 96.

The plate MI is provided with a vertically disposed plate I46 which engages in guide members I41 carried by the side walls I6 and I1. A clamping member I48 of resilient construction. which as shown in Figure 1 is longitudinally bowed is tensioned by means of a tensioning bolt I49 which is threaded into the bar I46 and the opposite ends 20f the clamping member I48 are adapted to engage against the guide members I41 so as to tightly hold the plate MI in adjusted position relative to the table 22. The forward side of the plate I46 is provided with a pair of stop members I50 on the upper ends of which the clamping member I48 is adapted to engage. The plate I4I is also braced by means of ribs I51 and I52 extending forwardly and rearwardly respectively of the plate I46..

A cover I53 engages on the upper edges of the side walls I6 and I1 and is provided on the opposite longitudinal edges thereof with downwardly extending flanges I54 which engage on the outer sides of the side walls I6 and I1 so as to frictionally hold the cover I53 on the housing I5. The lower ends of the side walls I6 and I1 are provided with feet I55 which are adapted to receive cushioning members I56.

In the use and operation of this dispensing machine, the roll of tape T is placed in the tape compartment I9 and then passed beneath the plate 28 in the guide-way 21 and then moved forwardly beneath the idler feed roll 15 and beneath the plate I33. The handle 68 maythen be swung forwardly in a counterclockwise movement so as to rotate the wheel 44 and draw the tape T beneath the knife I23 and'over the table 22. The under side of the tape T is adapted to have an-adhesive and this adhesive is moistened as the tape T passes over the upper end iii) of the brush 96. The handle 68 may be rotated to the limit permitted by the position of the stop II whereupon the handle is released permitting the spring 85 to return the handle 68 k to its initial position which is shown in Figure 3.

During the forward or feeding movement of the handle 68, the trigger I30 will move past the lever tripping member I29 raising the levers I26 in the slots I28 of the knife carrier ID'I.

When the handle 68 is released and is returned to its inoperative position by the spring 85 the trigger I 30 will strike the lever tripping members I29 so as to swing the opposite ends of the lever I26 downwardly. Downward movement of the levers I26 will move the knife carrier Ill'l downwardly and cause the knife I23 to cut off the tape at the forward end of the table 2|.

When the brush 96 is new this brush may at its upper end project above the table 22 and at this time the plate MI may be positioned so that the extensions I44 and M5 will not press unduly on the upper end of the brush 96. As the bristles of the brush 9B wear down or bend over, the plate I 4| may be lowered by releasing the clamping bar Hi8 and lowering the plate MI to the limit permitted by the ribs 25.

The plate MI and brush fit coact with the feeding wheels 54 and I5 in frictionally holding the tape T against movement relative to the slot between the table members 2i and 22 so that the blade or knife I23 will effectively sever the tape. This holding feature permits the use of only a single cutting blade which, in its cutting position, may be positioned in spaced relation to the longitudinal edges of the slot between the table members 2| and 22.

The length of the tape which is cut off by the knife I23 may be varied by rotary adjustment of the bearing member 5i. This is accomplished by loosening the thumb nuts 89 and then rotating the bearing 5| to the desired position indicated by the indicia l3. Rotary adjustment of the bearing 5| will adjust'the position of the handle stop II so that the handle 58 will be limited in its feeding movement.

A tape dispensing machine constructed according to this invention embodies the use of relatively few parts which are simple in construction and which may, therefore, be made more substantially than machines heretofore produced. As shown in Figure 2, all of the operating parts of this invention are enclosed in the housing I5 with the exception of the operating handle 68 so that the interior of the machine will not collect dust. The machine hereinbefore described embodies the use of a single knife blade I23 which has a V-shaped keen edge I24 thereby eliminating use of a stationary and a movable blade as is the case with a number of machines now in operation. In the event the blade I23 becomes dull it may be easily and quickly replaced by loosening the bolts I25 and inserting a new blade on the carrier IIl'I.
